The YC Spring 2026 deadline is approaching fast.

Y Combinator isn’t just about funding. It’s a launchpad.

You get $500K on founder-first terms, mentorship people like Sam Altman or partners who helped scale Airbnb, Stripe, and Scale AI; and access to a private network of 9,000+ alumni with $85B raised in follow-on capital.

If you’re early, scrappy, and building something people want, this is the most asymmetric bet you can make.

So I put together the updated YC Spring 2026 Application Pack.

All curated from real accepted applications, founder breakdowns, and current YC partner guidance to help you submit a clear, competitive application for this batch.


Framer is giving early-stage startups a full year of the Pro Plan: completely free.

What’s Inside the YC X26 Application Pack:

1. The 13 YC Application Principles That Actually Matter

A tactical guide to what YC really looks for, backed by advice from Paul Graham, Dalton Caldwell, and founders who got in successfully.

It includes the exact frameworks, application breakdowns, and insider advice founders used to get into Dropbox, GitLab, Martin, and more.

2. 50+ Successful Applications (Dropbox, GitLab, Paystack...)

A curated sheet with real YC applications from previous batches, including legacy names like Dropbox and GitLab, and newer ones like Paystack and KeyWords AI.

Use them as references to model your own.

3. YC Referral & Outreach Lists (Partners + Alumni)

Two separate private lists:

  • A YC partner list with emails, LinkedIn, Twitter/X, sector interests, and background

  • A 100+ YC alumni founder list from recent batches, mapped by company, sector, and focus

YC is huge on referrals. Built specifically for targeted outreach and potential referrals.

4. Question-by-Question Answer Guide by Martin, Bolto, Shogun and Fluently’s founders.

A doc-style walkthrough of the YC application, with practical advice on how to answer each question, straight from founders who got in (Martin, Bolto, Shogun, Fluently).

No fluff. Just clear, tactical pointers for every field.

5. YC Latest “Request for Startups”

A curated doc of the sectors and startup ideas they’re actively trying to fund right now.

Use this to sharpen your positioning or pitch a better idea entirely.

If you’re applying to YC this current batch, this is the most complete, battle-tested prep you’ll find.

Everything you need to write a top-tier application in one place.
